White to play. To cut or not to cut?

I could not make an informed decision

I'm the kind of player who'd be too scared to cut in an actual game. These days you can always ask to an AI which is always available for you with above any human strength. Leela thinks white must cut to win, and below is a continuation.

Always cut.

And I am saying that without having looked at the diagram.

I learned a "proverb" about this: "Cut first, think later"

Funny coincidence. On the same day I see a thread here about cutting, and I run into this on neural net go problems:
